A principle describing the effect of exciton bandwidths on the intensity of phonon sidebands in electronic spectra of molecular crystals is derived from some experimental observations, from some simple arguments, and from l &e quantum theory of electron-phonon coupling.

The phonon sidebands on the cscitons observed in certain molecular cryslals may be repres--nted by a ~e@tcd density of states. 11 is here shown qualjtatively and by reference to typical experiments that this function does not, in general, resemble the true density of state: b,Jt often may be predict

Radiation corrections for surface exiton levels in moIecuIar crystak are caIcuIared\_ It is shown that the frequency dependence of the luminescence and reflection spectra near a surface level is determined by the spectraI intensity of the local Iayer exiton correlator. In a general case the radiatio
